Considerations for successful therapeutic immunization in HIV cure.

Mothe, Beatriz; Brander, Christian

PURPOSE OF REVIEW In this special issue on human immunodeficiency (HIV) cure, we review the role of therapeutic immunization in strategies aimed to eliminate HIV-infected cells and/or mediate sustained control of viral replication in the absence of antiretroviral treatment. RECENT FINDINGS Recent data emerging from studies in simian immunodeficiency virus macaque models using broadly neutralizing antibodies, given alone or in combination with other immunomodulatory agents, as well as data from human clinical studies with novel therapeutic vaccines are showing encouraging results indicating that achieving viral remission or at least partial viral control of HIV without antiretroviral therapy is feasible. SUMMARY Although it remains unclear whether current strategies will be able to awaken a sufficient large fraction of the viral reservoir and/or vaccine-boosted immunity will induce effective, long-lasting viral suppression in chronically infected HIV population, emerging results establish cure strategies that can be further improved upon.
